Section IV. FUNGI
2-16. GENERAL
Fungi are members of the Plant Kingdom Mycetae (Fungi). Outstanding features of these eucaryptic microorganisms are the presence of cell walls, the lack of motility, and the absence of photosynthesis. Some exist as parasites on other living organisms whereas others are saprophytes, living on the remains of dead plants or animals. The term "fungi" includes the molds, yeasts, mildews, rusts, smuts, mushrooms, and toadstools. This group of organisms includes not only pathogenic species, but also several of important economic value. Molds of the genera Aspergillus and Penicillium are used in the manufacture of antibiotics. Certain molds of the same class are used in the production of cheese (Camembert, Roquefort, and so forth.). Yeasts are used in the production of alcoholic beverages and the baking industry. Edible mushrooms are considered a delicacy by connoisseurs of fine foods.
